Enhance surface properties, make repairs, restore tolerances, add protection.
The spray material in powder form is fed continually into a fuel gas-oxygen
flame where it is typically melted by the heat of combustion. A powder feed
carrier gas transports the powder particles into the combustion flame, and the
mixed gases transport the material towards the prepared workpiece surface.
It rapidly solidifies to form the coating. A cap that feeds compressed air
surrounds and appropriately shapes the flame.
